Gas pipeline upgrades to begin in Vincennes Vincennes, Ind. — Contract crews working for Vectren Energy Delivery (Vectren) will soon begin replacing gas mains and service lines in Vincennes as part of the company’s pipeline replacement program, which is a multiyear program to replace about 1,300 miles of bare steel and cast iron pipeline infrastructure throughout Indiana. In Vincennes, more than $3.6 million will go toward retiring nearly seven miles of gas main and approximately 500 service lines in 2016. Since 2008, more than 28 miles have been replaced within the city. Vectren intends to replace a total of approximately 80 miles in Vincennes over the next several years. “To ensure the continued reliability of our natural gas pipeline systems and service, Vectren has undertaken a program to replace essentially all of our bare steel and cast iron pipeline infrastructure,” said Brad Ellsworth, Vectren Energy Delivery of Indiana-South president. “These infrastructure enhancements are vital to meeting federal requirements and ensuring the continued safety of our system for decades to come.” Streets affected during the first project will include: Pineview Drive, Old Wheatland Road, McKenney Road, Monticello Drive, Harrison Drive, Washington Avenue, U.S. Highway 41, E. Old Highway 50, Bruceville Road and Belle Crossing. Visit the Active Projects tab on www.vectren.com/pipelinereplacement to view an interactive map displaying all streets in Vincennes where construction will take place. In most cases, a polyethylene (plastic) system is being installed to replace the current bare steel and cast iron gas pipeline system. First, the gas main will be replaced within the right-of-way, and then the service lines running directly to homes and businesses will be replaced. Upon completion of the project, affected yards, sidewalks and streets will be restored. “Construction for these pipeline projects may take several weeks to complete, and times may vary based on the size of the project, weather, ground surface/soil and other situations that may arise,” said Ellsworth. “Please be assured that Vectren and its contractors will make every effort to complete each project as quickly as possible and minimize impact to customers and the community.” Vectren reminds Vincennes residents to please keep the following in mind: 

Please exercise caution when driving through the construction zones.



We urge residents and their children to keep a safe distance away from any work zones.

Washington is one of nearly 75 cities in Indiana undergoing this type of pipeline replacement.
